Fig. 4From: Molecular monitoring of the diversity of human pathogenic malaria species in blood donations on Bioko Island, Equatorial GuineaAssociation between parasitaemia and sensitivity of diagnostic methods applied in this study. Median and interquartile ranges of non-cumulative P. falciparum parasitaemia are grouped according to different diagnostic tests used in this study (left y-axis, scatter plot). The dashed line at 100 parasites/µL represents the widely accepted LOD for RDTs. Proportional rates of positive blood donations are represented as bars (right y-axis)Back to article page
